Influence of fluorination time on surface flashover of epoxy in insulating gas [PDF]

open access: yes, 2015
The accumulation of charges on polymeric insulation under high voltage DC stress is a major concern in the transmission system as its formation distorts the local electric field and has an adverse impact on the electrical performance.

A review of advanced acoustic‐chemical‐optical partial discharge monitoring techniques for ultra‐high‐voltage gas‐insulated equipment

open access: yesHigh Voltage, Volume 10, Issue 4, Page 787-806, August 2025.
Abstract Partial discharge (PD) detection is considered one of the most crucial and effective methods for identifying defects in electrical equipment. Consequently, investigating advanced and efficient PD monitoring techniques is essential for the development of gas‐insulated equipment (GIE) and the construction of ultra‐high‐voltage (UHV) networks ...

Gas‐insulated switchgear partial discharge classification method based on deep transfer learning using experimental and field data

open access: yesHigh Voltage, Volume 10, Issue 4, Page 845-855, August 2025.
Abstract Gas‐insulated switchgear (GIS) plays a critical role in ensuring the reliability of power systems, but partial discharge (PD) is a primary cause of failures within GIS equipment. Traditional PD diagnostic methods rely heavily on laboratory data, which differ significantly from that under the complex conditions of field data, leading to a ...

Investigation of Partial Discharge in Solid Dielectric under DC Voltage

open access: yes, 2014
A partial discharge, or PD, is defined as an electrical discharge that is localized within only a part of the insulation between two separated conductors. Recent research on PD mainly focuses on the study of PD characteristics under AC voltage.
